Tire tread



FIG. 1 is a perspective view of a tire tread, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view thereof, the opposite side elevational view being identical thereof; and,

FIG. 4 is an enlarged fragmentary front view thereof.

In the drawings, the broken lines defining the inner bead of the sidewall and the peripheral boundary between the tire tread and the sidewall are for illustrative purposes only and form no part of the claimed design. The dark stippled surface shading represents the recessed portion of the tread grooves, having a depth as best seen in FIG. 2.
